jQuery 1.x

The jQuery 1.x line had major changes as of jQuery 1.9.0. We strongly recommend that you also use the jQuery Migrate plugin if you are upgrading from pre-1.9 versions of jQuery or need to use plugins that haven't yet been updated. Read the jQuery 1.9 Upgrade Guide and thejQuery 1.9 release blog post for more information.

The following CDNs also host compressed and uncompressed versions of jQuery releases. Starting with jQuery 1.9 they may also hostsourcemap files; check the site's documentation.

Note that there may be delays between a jQuery release and its availability there. Please be patient, they receive the files at the same time the blog post is made public. Beta and release candidates are not hosted by these CDNs.
